Efficacy and Safety of Sutureless Trabeculectomy with Using Porous Collagen (Ologen) in Management of Glaucoma Patients

Purpose: This study aims to investigate the safety, efficacy and feasibility of sutureless trabeculectomy using a porous collagen matrix that contains a connected porous structure (Ologen) in the control of intraocular pressure (IOP) in glaucoma patients. Methods: The study includes 25 eyes from 24 patients that met the inclusion criteria. All eyes underwent trabeculectomy with the Ologen implant that provides a space with a dynamic and physiological aqueous reservoir system. The operation was considered successful if IOP is <15 mmHg without need of IOP-lowering drops at 18 months of follow-up. Results: The target IOP was achieved in 21 out of the 25 eyes (84%), the remaining four eyes all had an IOP of 16 mmHg at 18 months. Short-term complications consisted of seven cases of bleb leakage treated with bandage contact lens and one case of mild choroidal effusion which resolved after observation alone. Conclusions: We can conclude that this technique can provide safety, effectiveness and short learning curve for ophthalmology trainees with lower incidence of perioperative and postoperative complications. Further studies may be required to prove stability and long-term efficacy in management of glaucoma patients.
